Comparative form of gulfy; more characteristic of or resembling a gulf.
From 'gulfy' (resembling a gulf) plus the comparative suffix '-er'. The base word 'gulf' comes from Old French 'golfe', from Greek 'kolpos'. The comparative suffix '-er' creates the comparative degree of the adjective.
This is the kind of word that shows how English lets us add suffixes to almost anything—if something looks more like a gulf, it's 'gulfier'! Most people today would just say 'more gulf-like,' but the '-ier' form follows the same rules as 'bigger' or 'smaller.'
